The New Mexico ER-1J Residential Journeyman Exam Questions and Correct Verified Solutions – Latest Updated Edition is a comprehensive study resource designed to help candidates prepare for the New Mexico ER-1J Journeyman Residential Wiring certification examinations administered through the New Mexico Regulation and Licensing Department (RLD) and PSI. New Mexico identifies ER-1J as the Journeyman Residential Wiring classification, which allows work under an ER-1 or EE-98 contractor license within the applicable scope. The resource covers the principal ER-1J electrical wiring topics, including general electrical knowledge, residential installation requirements, services, feeders, branch circuits, overcurrent protection, grounding and bonding, conductors and cables, raceways and boxes, special occupancies and equipment, pools, lighting, general-use equipment, low-voltage systems, and New Mexico electrical requirements. A major focus is the two-part ER-1J examination. The current PSI examination bulletin identifies Part 1 – Code as a 40-question examination requiring 75% (30 points) to pass, with 90 minutes allowed. Part 2 – Theory contains 25 questions, requires 75% (19 points), and allows 60 minutes. The Code Examination section emphasizes the 2020 National Electrical Code (NFPA 70) and the 2020 New Mexico Electrical Code (NMAC 14.10.4). Candidates review how to locate and apply residential electrical-code provisions involving installation requirements, conductors, raceways, grounding, overcurrent protection, services, feeders, branch circuits, and equipment. The study guide also covers services, feeders, and branch circuits, including conductor sizing, circuit requirements, load considerations, disconnecting means, panelboards, branch-circuit applications, and common residential installation scenarios. Another major section addresses overcurrent protection, including circuit breakers, fuses, conductor protection, equipment protection, and selecting appropriate protective devices for residential circuits. The material reinforces grounding and bonding, including grounding electrode systems, equipment grounding conductors, bonding requirements, grounding connections, and common residential electrical-system configurations. Candidates also review conductors and cables, including conductor identification, ampacity concepts, insulation, cable installation, termination, protection from physical damage, and appropriate applications for residential wiring. The guide includes raceways and boxes, covering box selection, conductor fill, raceway applications, fittings, cable entries, accessibility, support, protection, and installation practices. Special occupancies and special equipment, including residential swimming pools and related electrical installations, receive dedicated attention. Questions are designed to test recognition of special safety requirements and appropriate electrical installation practices. The resource also addresses lighting and general-use equipment, including luminaires, receptacles, switches, appliances, general-purpose circuits, installation requirements, and residential equipment connections. Low-voltage systems are another examination area. Candidates review basic requirements and installation practices for systems operating at lower voltages and the circumstances in which specialized requirements apply. The Theory Examination places greater emphasis on electrical principles and practical trade knowledge. The current PSI outline includes general electrical and installation knowledge, services/feeders/branch circuits, overcurrent protection, grounding and bonding, conductors and cables, raceways and boxes, special occupancies/equipment, lighting/general-use equipment, New Mexico State Code, and low voltage. The resource also supports preparation for residential troubleshooting and installation scenarios, helping candidates determine appropriate wiring methods, protection, conductor requirements, grounding methods, and equipment connections. New Mexico's current journeyman guidance identifies two years or 4,000 hours of experience for the ER-1J classification. PSI's experience-verification materials specifically describe residential electrical experience such as underground installation, rough-in installation, and trim-out work. Candidates should also understand the relationship between ER-1J and contractor classifications. Under the current proposed New Mexico rules, an ER-1J Journeyman Residential Wiring certificate holder can work under an EE-98 or ER-1 license, while the work performed must remain within the applicable contractor-license scope. For 2026 preparation, candidates should pay attention to current New Mexico RLD rulemaking. The Construction Industries Division has proposed amendments affecting journeyman certification and electrical classifications, so candidates should verify the applicable rules and examination bulletin before testing. The New Mexico RLD confirms that candidates register for Construction Industries examinations through PSI, and passing scores remain valid for one year after the examination. The resource should be treated as a study and practice resource rather than an official or leaked PSI examination. Claims that third-party materials contain “actual,” “verified,” or “just released” examination questions should not be interpreted as confirmation that they reproduce the secure ER-1J examination. Aligned with the current New Mexico ER-1J Journeyman Residential Wiring examination framework, this study guide supports preparation in NEC requirements, New Mexico electrical code, residential wiring, services, feeders, branch circuits, overcurrent protection, grounding and bonding, conductors, cables, raceways, boxes, pools and special equipment, lighting, general-use equipment, low voltage, and electrical theory. Ideal for New Mexico residential electricians, electrical apprentices transitioning toward journeyman certification, experienced electrical workers, electrical contractors, and candidates preparing for the ER-1J Journeyman Residential Wiring examinations, this resource provides focused review material, exam-style practice questions, and solution explanations to support effective preparation.
